Introduction: High sound, is an occupational and environmental hazard common.
Hospitals as medical and health care setting are affected by noise sources. Therefore, the
aim of this study is to investigate the noise pollution in Shiraz hospitals.
Methods: A cross-sectional study in different parts and the area around the 8 educational
and non-educational hospitals in Shiraz was performed. For all hospitals Indices Leq
(inside and outside), lmax, lmin, and SIL were measured in the morning, afternoon and night
by Sound level meter TES 1358. Data was analyzed by SPSS 16 and Test ANOVA and ttest
and Measurement Repetitive were performed.
Results: Average measured parameters Leq (inside and outside), lmax, lmin, and SIL in all
hospitals and in different shifts was more than limits of the country. The average leq
inside and outside were between 53 to 60 and 65 to 85 dB, respectively in teaching
hospitals and 49 to 58 and 48 to 71 dB in non-teaching hospitals were variable. Average
all parameters in teaching hospitals was more than for non-teaching hospitals.
Conclusion: In all sites and times of day and night, even at night shifts, the noise
pollution is a serious problem in all hospitals. Thus, engineering control and management
measures are recommended to improve the environment of medical and choice of
appropriate equipment.
